Amazing hamster cage made from a converted IKEA Detolf and quarter--circle corner shelves as the roof! I would want to add something extra to the lid to keep it from shifting, like from SoCal earthquakes or (more likely) inquisitive mousie noses.
A breathtaking outdoor Bunny Paradise! I love how you are able to spend time with your rabbits while actually being inside their habitat. This is the perfect idea, if you do not wish to bring your bunnies inside your house.
